JS2000 joystick
Description/theory of operation
JS2000 joysticks are low force, fingertip control joysticks. They are available in an X, XY and XYZ
configuration. The Z axis is accomplished with a twist grip. Two of three grip options may have a single,
momentary switch.
Hall effect sensors are used to measure shaft position. There are two independent sensors per axis on the
X and XY options and a single sensor per axis on the XYZ option. The nominal output signal range for the
X and XY axis sensors is 10% to 90% of joystick supply voltage. The nominal output signal range for the Z
axis is 25% to 75% of joystick supply voltage.
The PLUS+1®Compliant JS2000 function blocks supports the X, XY and XYZ versions of the joystick and the
optional grip button switch. The XYZ option is not supported.
The compliant function block algorithm uses one sensor input per axis to determine handle direction and
null position. The algorithm does not compare the dual sensor signals.
The compliant function block requires that the JS2000 joystick be supplied with 5 Vdc regulated sensor
power provided by a PLUS+1®control device.
